There are a ton of fishing knots out their that don’t need to be learned. There are a few important ones that are good to know that can save you time on the water, otherwise keep an app with knots handy on your phone for the knots that aren’t used much and are forgotten.
The Rapala Knot is great to use with attaching your fluorocarbon line (different fishing lines talked about here) to your lure. It gives your lure a more natural action with the loop not restricting the movement. It is a great knot. It holds very well. I haven’t had one fail on me yet. Knock on wood.
The Albright Knot is used to tie lines of different size together. I use this knot to tie my braided line to my fluorocarbon leader line. This knot is very strong and haven’t had this knot fail on me either. Like any fishing knot make sure you wet the knot when you cinch it down so it cinches down all the way. To make it extra sturdy you can put a drop of super glue on this knot to keep it from slipping. I did that for a little while then I stopped and I haven’t had an issue since I stopped using the super glue. So you don’t really need to use it, but for extra reassurance, just a dab will do ya.
The Gary Martin Knot is a great knot for swivels and fish hooks with eyelets large enough to get the doubled up fishing line through it.
If you can’t get the doubled up line through the hook then the Uni Knot is a great knot to use.
The two main knots I use are the Rapala Knot and the Albright Knot. Those knots are very easy to tie with a little practice. They also work great and hold great! Fishing line is fairly inexpensive and it is a good idea to practice tying knots at home so when your out on the water you know how to tie a knot or two. You never know when your line is going to get snagged on something on the bottom and you have to cut it and re-tie the leader to the line and your lure back on the end. If your good at tying line together this process takes a couple of minutes. If your bad at it then it could take you 5 or 10 minutes and the knots might not be right. As soon as you hook a fish and realize your knots didn’t hold your back to tying them again taking more time and possibly another wrong knot and all that could ruin a fun fishing day. Been there done that back in the day.
